    today I went to make a payment on my G26 and laid away a G20sf.been wanting a 10mm and I reload for it.but I am new to the sf deal.it was expalined that the distance in the trigger reach is shorter than the standard G20.it felt good I dry fired it a few times and I liked how it did.

    The store clerk was quite correct. The G20 SF (Short Frame) differs slightly from the standard Gen3 G20 frame in that the trigger reach distance of the SF grip is shorter by ~2-3mm from backstrap to trigger depending on how the caliper is positioned. The different dimensions of the grips are front-to-back only, the width of the grips are the same. There is no difference in the dimensions of the magazine cavity or mag catch mechanism, the G20 and G20SF use the same mags.

    Below are some more facts:

    Many find the feel of the SF grip to be remarkably different from the standard grip, and a few others can't tell much difference. It's something that only you can decide after holding both in your hand.

    Glock began producing the Gen3 G21SF and G30SF 45ACP pistols in 2007 and 2008, respectively. The Gen3 G20SF and G29SF 10mm pistols followed in January, 2009. All are marked with the letters "SF" on the right side of the frame forward of the slide lock.

    The SF pistols have a different trigger mechanism housing (TMH) than the standard frame to fit in the slightly smaller frame cavity, but the ejector, trigger with trigger bar, connector, and trigger spring are identical to those in the standard frame.

    The TMH for the 45ACP/10mm Gen3 SF pistols (and Gen4 models) is shown below on the left (Part No. SP 5406). Note the pointed taper and notch at the bottom allowing it to fit in the smaller frame cavity of the SF pistol. The TMH for the standard frame Gen3 45ACP/10mm pistols is shown on the right for comparison (Part No. SP 8203).

    All the Gen3 45ACP and 10mm pistols (standard and SF) use the 8196-2 ejector. The same ejector is found in the Gen4 45ACP/10mm models as well. When viewed from above, the 8196-2 ejector has an S-shaped bend.

    There are no differences in the slide or barrel of the two current Gen3 variants of the pistols (std. and SF). Both perform equally well.

    Suppliers of aftermarket parts provide separate models of various optional accessories that interface with the grip such as grip plugs, grip-mounted lasers, magwell adapters and beavertail adapters that fit only the standard frame or the SF pistol. They are not interchangeable.

    Not sure whether your question was answered in this thread, but I think you will like the 20SF.
    I have shot the 20 and 21 for years, and yes, I can say that the Short Frame G20 is considerably easier for me to shoot well.
    BTW, the Gen4 without the added backstrap(med or large) fits me a bit better than even the SF!
    :cool:

    Man... the only thing better than my 20sf would be a 20 gen4! I absolutely LOVE the feel of my 21 gen4!!! If I ever find a 20 gen4 I might end up trading out my 20sf for one....
